Thank you for trusting JustAnswerDear FriendMy name is Sebastien and Listen To your question.
Friend the problem presented is in the brake caliper.
the failure is by brake pressure hose clogged or blocked
has to check the pressure and bleed the system all cylinders should have good pressure at the time of the purge
when one side has low pressure causes slow when you go sideways, either by dirt, sediment or obstruction in the system.
Nice to be able to serve friend, thanks for your attention, please be kind enough to assess the response as it is important for my profile.atteSebastien.
If you have concerns or questions that I present to you order.
